DigiGrade – developed by and exclusive to VeriVide – automatically grades colour fastness test samples digitally. This small footprint system essentially comprises of a digital camera linked to DigiEye’s software to give objective, accurate, consistent and rapid results.
DigiGrade can assess single or multiple samples and is fully compliant with BS EN ISO 105-A11:2012 Textiles – Tests for colour fastness. Part A11; Determination of colour fastness grading by digital imaging techniques (measures 3D surfaces, non-uniform shades, uneven staining).
Though this is extremely advanced technology, the DigiGrade system is easy to use without specialist skills or knowledge. Typically, operators can be trained to good proficiency levels within a day. A major advantage of DigiGrade is that it is a non-contact system. Examples of its use are the assessment of wash fastness grading for change of shade and staining, light fastness and rubbing.
